In order to make the technical solution of the utility model clearer, clear, be described in further detail below in conjunction with accompanying drawing.
Embodiment
The utility model embodiment solution mainly is the isolation projection that is provided for retarder by integrated mode on magnet ring, substitutes spacer additional in the prior art, obtains novel common mode inductance or magnet ring.As shown in Figure 3, the utility model one embodiment proposes a kind of common mode inductance, comprises magnet ring 1 and is wrapped in coil 2 on the magnet ring 1, magnet ring 1 comprises magnet ring body 10 two isolation projectioies 11 integrated with it, and it is one-body molded that its middle magnetic ring body 10 and isolation projection 11 can be passed through the mold mode.Isolate projection 11 for two on the described magnet ring 1 and be positioned on the symmetric position of magnet ring body 10, the symmetric position on its middle magnetic ring body 10 shows as the straight lines that connect two isolation projectioies 11 arbitrarily can be by the ring heart of magnet ring body 10.
Among the utility model embodiment,, make in winding around 2 that isolation projection 11 has just played separates the function that coil 2 is avoided its contact because magnet ring 1 has above-mentioned isolation projection 11.Wherein, isolate projection 11 and can be cube or cylinder or tetrahedron, or other can play the shape of retarder 2.In one embodiment, isolate projection 11 and be positioned at magnet ring 1 inner surface 12.In addition, isolate projection 11 and also can be positioned on other positions of magnet ring body 10, as the outside 13 or the transverse plane of magnet ring 1, for example on front 14 or the back 15.Particularly, can isolate projection 11 and be positioned on the front 14 of magnet ring body 10 with reference to Fig. 4 and shown in Figure 5.
As shown in Figure 6 and Figure 7, be the structural representation of embodiment three of the present utility model.Isolate projection 11 and interconnect for two on its middle magnetic ring 1 inboard 12, one of them isolation projection 11 extends on the another one isolation projection 11 symmetrical with it and becomes one, this structure of this embodiment can be separated coil 2 fully, plays the effect of epoxy dividing plate 4 as shown in Figure 2.
The utility model also provides a kind of magnet ring 1, described magnet ring 1 comprises magnet ring body 10 and two isolation projectioies 11, isolating projection 11 for these two is symmetricly set on the magnet ring body 10, it is one-body molded that magnet ring body 10 and two isolate projection 11, its middle magnetic ring body 10 with two to isolate protruding 11 preferential application mold modes one-body molded.Isolate projection 11 for two and be positioned on the symmetric position of magnet ring body 10 inner surfaces 12, the symmetric position on its middle magnetic ring body 10 shows as the straight lines that connect two isolation projectioies 11 arbitrarily can be by the ring heart of magnet ring body 10, as shown in Figure 3.
Isolating projection 11 for two can also interconnect, and one of them isolation projection 11 extends on the another one isolation projection 11 symmetrical with it and becomes one, as shown in Figure 6 and Figure 7.
